LABEL DESCRIPTION
RIP & Multicast
Setup
RIP Direction RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to
exchange routing information with other routers. The RIP Direction field controls
the sending and receiving of RIP packets. Select the RIP direction from Both / In
Only / Out Only / None . When set to Both or Out Only , the ZyXEL Device will
broadcast its routing table periodically. When set to Both or In Only , it will
incorporate the RIP information that it receives; when set to None , it will not send
any RIP packets and will ignore any RIP packets received.
RIP Version This field is enabled if RIP Direction is not None . The RIP Version field controls
the format and the broadcasting method of the RIP packets that the ZyXEL Device
sends (it recognizes both formats when receiving). RIP-1 is universally supported
but RIP-2 carries more information. RIP-1 is probably adequate for most networks,
unless you have an unusual network topology. Both RIP-2B and RIP-2M sends the
routing data in RIP-2 format; the difference being that RIP-2B uses subnet
broadcasting while RIP-2M uses multicasting. Multicasting can reduce the load on
non-router machines since they generally do not listen to the RIP multicast address
and so will not receive the RIP packets. However, if one router uses multicasting,
then all routers on your network must use multicasting, also.
Multicast IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group. The ZyXEL Device supports both IGMP
version 1 ( IGMP-v1 ) and IGMP-v2 . Select None to disable it.
Any IP Setup Select the Active check box to enable the Any IP feature. This allows a computer to
access the Internet without changing the network settings (such as IP address and
subnet mask) of the computer, even when the IP addresses of the computer and
the ZyXEL Device are not in the same subnet.
When you disable the Any IP feature, only computers with dynamic IP addresses or
static IP addresses in the same subnet as the ZyXEL Device’s LAN IP address can
connect to the ZyXEL Device or access the Internet through the ZyXEL Device.
